Direct measurements of equivalent beam angle on hull-mounted transducers
(ICES CM Documents;1985/B:43, Working paper, 1985)Measurements for checking the equivalent beam angle on a hullmounted transducer have been made on a standard 38-29/25-E SIMRAD transducer on the Norwegian research vessel "ELDJARN". The measurements were made during a ... -
Directional properties of an 18-kHz transducer
(ICES CM Documents;1993/B:29, Working paper, 1993)Several theoretical measures of directivity are given for an 18-kHz transducer that is used in both single-beam and split-beam applications, namely the SIMRAD transducer type 18-11 in the single-beam variant. These are ... -

Discrimnation of herring populations in a northern Norwegian fjord: genetic and biological aspects
(ICES CM Documents;1986/H:63, Working paper, 1986)From a trawl survey in a fjord system in northern Norway, it has been possible to separate catches of herring into two distinct groups characterized by different number of vertebrae (VS). Low- vertebral herring (VS = ... -

Dispersal and By-Catch Mortality in Grey, Halichoerus grypus, and Harbour, Phoca vitulina, Seals Tagged at the Norwegian coast
(ICES CM documents, Working paper, 2000)The results of the study presented here are submitted to a refereed journal for consideration. The review and printing process may not be completed at the time of the 2000 ICES Annual Science Conference and the subsequent ... -
Distinguishing between spring and autumn spawned herring from daily increments, a preliminary report
(ICES CM Documents;1988/H:15, Working paper, 1988)Otoliths from Norwegian Spring Spawning herring larvae, collected on a cruise in May 1985 and North Sea Autumn Spawned herring larvae, collected on a cruise in Desember 1987, were examined for daily increments. A greater ... -
Distribution and abundance of 0-group Norway pout and haddock in the North Sea july - august 1978
(ICES CM documents, Working paper, 1979)In order to assess the 0-group abundance of Norway pout and haddock in the North Sea a combined acoustic/trawl survey was carried out in July - August 1978. The 0-group of both species were concentrated in a scattering ... -
Distribution and abundance of sprat in the North Sea in winter 1979-1980 determined by acoustic methods.
(ICES CM Documents;1980/H:41, Working paper, 1980)To estimate the size of the North Sea sprat stock acoustically two cruises were carried out in November 1979-January 1980. The method is described and the size of the sprat stock was estimated to about 1 million tons. ... -

Distribution and growth of blue whiting in the north-east Atlantic
(ICES CM Documents;1990/H:14, Working paper, 1990)The distribution pattern of the blue whiting spawning stock has gradually changed in recent years, and concentrations are recorded more offshore and more to the south than before. The activity of the fleet with its ... -
Distribution and growth of capelin in the Barents Sea in relation to water temperature in the period 1974 to 1983
(ICES CM Documents;1984/GEN:16, Working paper, 1984)The variation in the distribution of the different age-groups of capelin in the Barents Sea were studied in relation to temperature variation in the period 1974 to 1983. In addition, growth of the capelin were compared ... -
Distribution and migration of the 1983 year class of Norwegian spring spawning herring in the period July 1987 - August 1988
